バイパスバルブ。 In a bypass valve interposed between a hydraulically actuated member having first and second hydraulic pressure supply ports and a switching valve having first and second ports, the bypass valve has the first hydraulic pressure. A first passage connecting the supply port and the first port, and a second passage connecting the second hydraulic pressure supply port and the second port are formed, and these first and second passages are connected. A bypass valve that communicates through a passage, the communication passage being opened and closed by a manually operated valve body, and further having an oil chamber connected to a hydraulic pressure generation source formed on the back side of the valve body.
